You can now add tags to your AWS Lambda functions. Using tags, you can now add metadata to each of your functions. Each tag consists of a key and value. You can use these tags to allocate costs from your AWS bill to individual functions. There is no additional charge for tagging your Lambda functions.

Previously, you needed to build custom solutions or use log analysis in order to organize, filter, or allocate your costs by function. Now, you can easily organize your functions into groups and filter them by tag using the Lambda API and Lambda console.

This feature will become available in all AWS Lambda regions within 24 hours. Visit the documentation to learn more about using cost allocation tags. Please visit our product page for more information about AWS Lambda or log in to the AWS Lambda console to get started.
